SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE SUSQUEHANNA STEAM ELECTRIC STATION, UNITS 1 AND 2, LICENSE RENEWAL APPLICATION
Dear Mr. Spence:
By letter dated September 13, 2006, PPL Susquehanna, LLC submitted an application pursuant to Title 10 of the Code of Federal Regulation Part 54 (10 CFR Part 54), to renew the operating licenses for Susquehanna Steam Electric Station, Units 1 and 2, for review by the U.S. Nuclear Regulatory Commission (NRC or the Staff). The staff is reviewing the information contained in the license renewal application and has identified, in the enclosure, areas where additional information is needed to complete the review. Further requests for additional information may be issued in the future.
Items in the enclosure were discussed with Duane Filchner, and a mutually agreeable date for the response is within 30 days from the date of this letter. If you have any questions, please contact me at 301-415-4029 or by e-mail evelyn.gettys@nrc.gov.
Sincerely,
/RA/
Evelyn Gettys, Project Manager Projects Branch 1 Division of License Renewal Office of Nuclear Reactor Regulation Docket Nos. 50-387 and 50-388

SUSQUEHANNA STEAM ELECTRIC STATION UNITS 1 AND 2 LICENSE RENEWAL APPLICATION REQUEST FOR ADDITIONAL INFORMATION (RAI)
RAI 3.3.2.2.6-2 In the RAI response dated August 15, 2008, on page 28/49 there is mention of decay products.
Please describe these decay products.
RAI 3.3.2.2.6-3 In the RAI response dated August 15, 2008, on page 29/49 there is a table titled, SSES Spent Fuel Pool Boral Average B-10 Areal Density Results. From this table, the staff has the following questions:
- a. How many coupons are left in each pool? Please discuss the schedule for coupon removal and testing during Susquehannas period of extended operation to demonstrate continued Boral performance.
- b. How can the projected value at year 2015 for the Unit 2 areal density result be higher than any value actually measured during the first 30 years of service?
RAI 3.3.2.2.6-4 In the RAI response dated July 24, 2008, it states that, SSES does not monitor for nor have plant-specific operating experience regarding the presence of aluminum cations in the spent fuel pool. Please explain why SSES does not monitor for aluminum cations when there is industry operating experience of aluminum dissolving from Boral panels in spent fuel pools. Also, please describe how the Water Chemistry Program monitors for and mitigates the loss of neutron absorbing material in the spent fuel pool.
RAI 3.3.2.2.6-5 In September 2003, inspection of Boral test coupons at Seabrook Nuclear Station revealed bulging and blistering of the aluminum cladding. Please discuss the impact, if any, that this event is considered to have on the surveillance of Boral at Susquehanna. Industry experience has indicated that during long term exposure such blisters may form. Also, in the RAI responses, it states, These vented samples have shown blistering near the edges of the plate due to the porous nature of the cut edge of the plate, where water interacts with the Boron matrix and radiation to generate gases that blister the plate. This effect has, in some cases, caused the outer metal layer of the Boral plate (sample) to blister out and press flat against the outer tube that contains it. Since formation of blisters may affect the efficiency of the Boral panels to attenuate neutrons (through flux trap formation) and may cause deformation of the fuel storage cells, the applicant should explain why blistering of the Boral panels will not be a safety concern in its plant.
RAI 3.3.2.2.6-6 Please discuss any other operating experience that may be applicable to Susquehanna and describe why it would not be a safety concern.
